Current conditions of new advanced materials production impose the application of industrial wastes from iron-ore deposits as a prospective component for building materials. A great potential of the wastes utilization found in autoclave building materials. Therefore, the effect of the ferriferous mineral admixture hematite Fe2O3 as a main component of iron-ore wastes on phase and structure formation in binder under autoclave curing as well as physical and mechanical characteristics was studied in this research. The optimal content of Fe2O3 and autoclave regime, forming hydrosilicates with ferrous components inclusion can increase strength performance of autoclave silicate composite. SEM and XRD were used in this study to analyze the microstructural and chemical characteristics. The presence of ferriferous components in the lime-silica binder system causes an increase of low-basic calcium hydrosilicates formation like 11Ǻ-tobermorite as well as formation of ferrous hydrogarnets in form of dendroid aggregates. The optimal amount of the mineral admixture Fe2O3 in the lime-silica binder was found to be 5% that provides the 13% boost of compressive strength.
